Men Who Gain Weight At Risk Of Prostate Cancer

Men who gain weight as young adults are at heightened risk of developing prostate cancer according to a new study.

Researchers from the University of Hawaii reported that obesity is a risk factor for many common cancers, including colorectal cancer and breast cancer in postmenopausal women. However, whether obesity plays a role in prostate cancer risk has been unclear, researchers say.

The new study finds that body mass in both younger and older adulthood, and weight gain between these periods of life, may influence prostate cancer risk. There are some 1.4 million new cases of cancer diagnosed each year in the United States according to the American Association for Critical Illness Insurance. Over 565,000 Americans die from cancer each year.

The researchers collected data on almost 84,000 men. The study also examined the relationship between weight and prostate cancer in a multiethnic population including blacks, Japanese, Hispanics, Native Hawaiians and whites. Men who were overweight or obese at 21 had a lower risk of localized and low-grade prostate cancer, the researchers found.

The study findings revealed that when men put on weight seemed to matter, as did race and ethnicity. Higher weight in older adulthood was associated with increased risk of prostate cancer among white and Native Hawaiian men and a decreased risk of prostate cancer among Japanese men.
